About Baengnyeongdo

Baengnyeongdo is the largest inhabited island of an archipelago in the Yellow Sea administered by Incheon, South Korea. It lies near the maritime boundary with North Korea and is known for both its strategic location and wildlife.

The island draws visitors for birdwatching, coastal scenery and fishing communities, with seasonal migratory birds and marine life along its shores. Short hiking routes and viewpoints provide views across the Yellow Sea toward the Korean Peninsula.

The island has been settled for centuries and in modern times has strategic military significance due to its proximity to the Northern Limit Line and North Korea. Civilian life has continued alongside military installations and regular ferry connections to the mainland.

Baengnyeongdo sits in the Yellow Sea off Korea’s west coast, administratively part of Ongjin County, Incheon, and is one of the westernmost populated South Korean islands.

  • Border proximity: Located very close to the maritime boundary with North Korea, the island has military facilities alongside civilian settlements and ferry services connect it to the mainland province of Incheon.
